Socketspipeflush

Socket pipe plugs are flush-seating plugs with tapered threads that extend the full length, designed to provide a flush fit in a standard tapped hole. They have flat ends chamfered at 45 degrees, with identification grooves. A high pressure seal is achieved through the difference in taper between the plug and tapped hole. Socket pipe plugs are preferred for high pressure applications where protrusion is undesirable. They are made of high grade alloy steel and heat treated to be hardened.

*Taper reaming after drilling is recommended for tapping ease and to give fully formed, uniform threads.

A flush type plug is one having a tapered (0.875”diametral per 12”) thread extending its entire length and designed to provide a flush condition with
a standard tapped hole (0.750” diameter per 12”). Both ends of the plug shall be flat and chamfered approximately 45°. The chamfer shall extend
Description slightly below the root of the thread, and the edge between flat and chamfer shall be slightly rounded. Six equally spaced identification grooves are
located equidistant between corners of the hex socket and edge of the chamfer (Note: On the 1/16-27 plug, 3 identification grooves are permitted
because of limited space).

A high pressure seal is achieved through the difference in taper, with dimensions precalculated to provide a higher sealing load near the large end
Applications/ of the plug and the threads near the top of the tapped hole. The flush type plug is preferred where high pressures are encountered and where
